Communication involves the sharing of information between two parties who have something in common. It is a continuous process that includes a sender encoding a message, a medium to transmit the message, a receiver who decodes and understands the message, and potential feedback or noise. There are three main types of communication: non-verbal communication which involves facial expressions and body language; verbal communication which uses spoken or written language; and visual communication which uses graphical representations to efficiently convey meaning, such as in websites, presentations, or social media posts. Communication also has certain inherent properties - it involves communicators, is irreversible, is proactive, is a social process, involves individual interpretation of meaning, and relies on symbolic interaction.
